Organizing the library

Hello everybody. I´ve seen that when I browse user´s files, most part of the users have really tidy folders, usualy organized by artists-discs etc. I have a quite big music library, and everything tagged in itunes. The problem is that my files (wich people would see when they browse me) are really messy. I guess that the metadata of files is fine, but the actual organization in windows explorer of these files doesen´t reflect this. Does anyone know how can I solve this without having to expend a lot of time editing everything? I just want to make it easier to share.
